UNITED STATES PATENT OFFICE DAVID B. DOW, OF GIBBON, NEBRASKA.

SKATE-SHARPENER.

To all whom it may concern:

Be it known that I, DAVID B. Dow, a citizen of the United States, residing at Gibbon, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Skate-Sharpeners, of which the following is a specification.

The present invention relates to an improved device for sharpening skates and the primary object of the invention is the pro vision of a skate sharpener which can be conveniently carried upon the person and which can be readily applied to the runner of a skate for the purpose of sharpening the same.

The invention further contemplates a de vice of this character embodying a novel construction which admits of the abrading member being moved to bring various portions thereof successively into operative position as desired, and which will leave the skate runner with a slightly concave surface.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a side elevation of the improved skate sharpening device. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a transverse sectional view. Fig. 4 is an end view.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the casing within which the abrading member is mounted, the said casing bein formed with a longitudinal slot and outwardly extending spaced and parallel flanges being located upon opposite sides of the slot, the said flanges belng designed to receive the skate runner between the same and to guide the device in its longitudinal movements along the runner. In the pres ent instance the casing l is cylindrical in shape and is shown as formed -from a single strip of material the edges of which are extended outwardly to form the guide flanges 2. Brackets 3 and 4 are applied to opposite Specification of Letters Patent.

ends of the casing 1 and the said brackets are formed with arms 5 which embrace the casing and are detachably secured thereto by any suitable means such as the screws 6.

The abrading cylinder '7 is arranged within the casing 1 so that a portion of the surface thereof is exposed to the space between the guide flanges. One end of the abrading cylinder is formed with a pivot stud 8 which is journaled within the bracket 3 while the op osite end is provided with a square or angu ar stud 9 which is received within a corres onding opening in the bracket 4. It will t us be obvious that as long as the bracket 4 is in position the abrading cylinder will be held against rotation and locked securely in position, while by removing the said bracket 4 the abrading cylinder may be turned so as to bring a different portion of the surface thereof into operative position. In the preferred construction the abrading cylinder is in the nature of a file, the surface thereof being roughened in a manner identical with that of such an implement, and the said abrading cylinder tapers slightly toward its opposite ends so that every portion thereof can be brought effectively into contact with the skate runner.

In the operation of the device the skate runner is inserted between the guide flanges 2 until it is brought into contact with the ex posed surface of the abrading cylinder 7 and the device is then moved longitudinally back and forth upon the runner, the cylinder serving to sharpen the runner in the usual manner and leaving the same with a slightly concave surface. As soon as the exposed portion of the abrading cylinder becomes worn it is merely necessary to temporarily remove the bracket 4 and turn the abrading cylinder to bring another portion of the roughened surface thereof into operative position.

Having thus described the invention, what is claimed as new is:

The herein-described skate sharpener comprising a cylindrical casing formed with a slot, guide flanges projecting outwardly from the casing upon opposite sides of the slot, an abrading cylinder arranged. within the casing and of such a size as to move freely therein, one end of the abrading cylinder being formed with a pivot stud while the opposite end is formed with an angular stud, and a ceiving the angular stud of the abrading cylbracket detachably applied to each end of inder to hold the cylinder against movement. 10
